i ve noticed since 2years ago i got massive lagg on summer time and i was wondering why?!!
last year i find out after i hired someone to reformat my laptop's window.
COS the heat the internal cooler can't cool by himself ur laptop, meaning heated processor meaning LAGG
COS the nub me didnt asked for a service to clean the fan from dust wich made the cooler work harder and cool slower the internal parts of laptop.
This year summer come again and me nub , forgot thouse notes... i lagged again, untill my girlfriend QQed about her own laptop and that when she went to check laptop to service, they said her internal fan is broken cos wasnt cleaned in time.
Then i remended AAAAAAAAAAAAAAAAH! and i open my laptop (remembering the steps the guy did 1 year ago) and i cleaned my fan...
guess what less laggggggg
and after that i bought an external fan callled Notebook Cooling Pad, with USB connection and guess what the cooler gets cold air from that external fan and cool the procesor...
results: a happy and cool procesor
and i adjusted my laptop setings as u named up
